hey everone,
I am doing a torque converter upgrade on my c4 and was wondering if anybody had any suggestions to what stall speed i should use. I have a mild 302 with a comp cams extreme energy camshaft(specs)
, holley 670 cfm carb, highflow heads with 1.94 on the intake and 1.6 on the exhaust. My rear end is in need of a future upgrade, and it currently has what i believe to be about 2.79's with and open differental. I am looking to upgrade that to 3.55's. thanks matt

 

my setup is very close to yours, i went with a 2500 stall and wish i had gone bigger like 3000

 

This is the same cam I put in my 302 68 Fastback.
I really liked it. Good idle. Great midrange.
I had a T-5 tranny though. 3.25 gears in back.

I would not go with more than 500rpm over stock for a street driven car, with 3.50 gears. A fluid cooler would be a good investment also.
